A vulnerability was found in Unbound. The issue arises due to a flaw in the handling of Extended DNS Error (EDE) records when the ‘ede: yes’ option is enabled, a non-default configuration. Specifically, an unchecked condition in the code can trigger an infinite loop when attempting to trim the text fields of EDE records to fit within the client’s buffer size. This vulnerability could potentially lead to denial of service (DoS) as the infinite loop consumes system resources, impacting the availability of the Unbound DNS resolver.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
